Pathophysiology and Natural History
S. aureus is the usual pathogen, although exposure to Pseudomonas aeruginosa in hot tubs or swimming pools can lead to folliculitis. In general, folliculitis is a self-limited entity. Occasionally, a pustule enlarges to form a tender, red nodule (furuncle) that becomes painful and fluctuant after several days. Rupture often occurs, with discharge of pus and necrotic material. With rupture, the pain subsides and the redness and edema diminish.
